Mr Harrison’s role as a Labour Party deputy chief whip charged with keeping Harold Wilson’s minority 1974 government in power is currently the subject of a national Theatre stage show.

Ashes to Ashes TV star Philip Glenister is playing Mr Harrison in the production called This House.

The efforts of Mr Harrison and fellow whip Bob Mellish to keep the government going despite the lack of a majority and having to deal with crisis after crisis have passed into Westminster legend.

And as deputy chief whip in the late 1970s, Mr Harrison was the unsung hero of a series of knife-edge votes in which Jim Callaghan’s minority government just managed to scrape home.

Former electrician Mr Harrison served with the Royal Air Force in World War II. When given the Freedom of the City of Wakefield in 2003, he said: “I am delighted and honoured to be given the Freedom of the City which I love so much.”
